Hi
I have a problem on a MPC8266 with 512MB or RAM
If I boot Linux (2.4.21rc1) with the full amount of memory, it hangs
right after initializing kswapd
If I reduce the amount of memory (either by using a 256MB stick or
adding mem=0x1e000000 to the boot args) the kernel boots normally
Non working log:
